When studying the brains of psychopaths with an MRI, they tend to have a very thin amygdala. That is the part of the brain that is responsible for human emotion, and stored memories of what you need to be afraid of. In a laboratory study, when the amygdala is removed from a rat’s brain, they will never run away. They’ll even climb on top of a cat.

That includes getting caught by the police, or the possibility of spending life in prison.

  • Anyone who has been in love knows how addictive that uplifting, happy feeling can be. Well, the chemical in your brain that causes love is called “dopamine.” This chemical also causes those passionate feelings of lust, the urge to gamble, and motivation for success.

So they’re pretty much addicted to feeling that excited dopamine rush all the time. If life is just “OK”, and they’re they’re not feeling some kind of satisfaction from “winning” something, they find other ways to satisfy their addiction–like manipulating people into get what they want.

  • In 2012, there was a scientific study on emotions of psychopaths. First, researchers showed video clips of various emotional interactions, and they felt nothing. They even slapped them on the back of their hands with a plastic ruler, which is very painful, and yet their brain didn’t register the pain. Then, they asked the test subjects to try to empathize with the emotions in some video clips. They showed scenes of someone being beaten and abused. Finally, the section of the psychopath’s brain with memories of pain lit up on the MRI. These scientists have theorize that maybe psychopaths have an “on and off switch” for their emotions, and they have been through so much abuse during their childhoods, that they simply choose to keep the lights off.
